Description

Die Erfindung betrifft eine Batterie für ein Fahrzeug, wobei die Batterie eine Anzahl von zu Modulen zusammengefassten seriell und/oder parallel miteinander verschalteten Einzelzellen aufweist, welche in einem Batteriegehäuse angeordnet sind.The invention relates to a battery for a vehicle, wherein the battery has a number of modules combined in series and / or parallel interconnected individual cells, which are arranged in a battery housing.

Für jede Antriebsbatterie eines Fahrzeuges, insbesondere eines Hybridfahrzeuges oder eines Elektrofahrzeuges kann im Kollisionsfall des Fahrzeuges in Anstoßrichtung ein hohes Gefährdungspotential durch Deformation der Antriebsbatterie bestehen. Oftmals sind Einzelzellen der Antriebsbatterie zu größeren Baugruppen, beispielsweise Modulen, zusammengefasst. Im Kollisionsfall des Fahrzeuges besteht die Gefahr, dass einzelne Module und somit auch Einzelzellen beschädigt werden und dadurch elektrochemische Substanzen aus den Einzelzellen austreten können und somit ein Gesundheitsrisiko für Fahrzeuginsassen und/oder Personen im unmittelbaren Umfeld zu der Antriebsbatterie bestehen kann.For each drive battery of a vehicle, in particular a hybrid vehicle or an electric vehicle, there can be a high risk potential due to deformation of the drive battery in the event of a collision of the vehicle in the direction of impact. Often, individual cells of the drive battery are combined to form larger assemblies, such as modules. In the event of a collision of the vehicle, there is the risk that individual modules and thus also individual cells will be damaged and thus electrochemical substances can escape from the individual cells and thus pose a health risk for vehicle occupants and / or persons in the immediate vicinity of the drive battery.

Der Erfindung liegt die Aufgabe zugrunde, eine verbesserte Batterie für ein Fahrzeug anzugeben.The invention has for its object to provide an improved battery for a vehicle.

Die Aufgabe wird erfindungsgemäß durch die in Anspruch 1 angegebenen Merkmale gelöst.The object is achieved by the features specified in claim 1.

Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.

Eine Batterie für ein Fahrzeug weist eine Anzahl von zu Modulen zusammengefassten seriell und/oder parallel miteinander verschalteten Einzelzellen auf, welche in einem Batteriegehäuse angeordnet sind. Erfindungsgemäß sind die Module im Kollisionsfall des Fahrzeuges, insbesondere bei einer Heck- oder Frontalkollision, in dem Batteriegehäuse in Stoßrichtung verschiebbar.A battery for a vehicle has a number of modules connected in series and / or parallel interconnected individual cells, which are arranged in a battery housing. According to the invention, the modules are in collision case of the vehicle, in particular in a rear or frontal collision, slidable in the battery housing in the direction of impact.

Dadurch, dass die Module verschiebbar innerhalb des Batteriegehäuses angeordnet sind, ist in besonders vorteilhafter Weise ein Risiko einer Beschädigung im Kollisionsfall des Fahrzeuges verringert, da sich die Module durch eine Deformation des Batteriegehäuses und/oder aufgrund ihrer Masseträgheit im Kollisionsfall verschieben.Characterized in that the modules are arranged displaceably within the battery case, a risk of damage in the event of a collision of the vehicle is reduced in a particularly advantageous manner, since the modules move by a deformation of the battery case and / or due to their inertia in case of collision.

Da eine Beschädigung von Modulen, d. h. von Einzelzellen durch Verschieben der Module im Kollisionsfall weitestgehend ausgeschlossen werden kann, ist auch ein Risiko thermischer Ereignisse bezogen auf beschädigte Einzelzellen nahezu ausgeschlossen. Da das Risiko thermischer Ereignisse weitestgehend ausgeschlossen ist, ist ein Gesundheitsrisiko für Fahrzeuginsassen und Personen im unmittelbaren Umfeld der Batterie durch leicht flüchtige Bestandteile einer in den Einzelzellen befindlichen elektrochemischen Substanz zumindest verringert.Since damage to modules, i. H. Individual cells can be largely excluded by moving the modules in the event of a collision, a risk of thermal events based on damaged individual cells is almost impossible. Since the risk of thermal events is largely ruled out, a health risk for vehicle occupants and persons in the immediate vicinity of the battery is at least reduced by volatile constituents of an electrochemical substance present in the individual cells.

Zudem ist vorgesehen, dass eine Verbindung zwischen den Modulen und einer Batterieüberwachungseinheit trotz Verschiebens der Module bestehen bleibt, wodurch folglich eine Diagnosesicherheit zumindest hinsichtlich der Module weiterhin sichergestellt ist.In addition, it is provided that a connection between the modules and a battery monitoring unit remains despite moving the modules, which consequently further ensures diagnostic reliability, at least as regards the modules.

Ausführungsbeispiele der Erfindung werden im Folgenden anhand einer Zeichnung näher erläutert.Embodiments of the invention will be explained in more detail below with reference to a drawing.

Dabei zeigt:Showing:

1 schematisch eine Schnittdarstellung einer Batterie für ein Fahrzeug. 1 schematically a sectional view of a battery for a vehicle.

In der einzigen Figur ist ein Querschnitt einer Batterie 1 für ein Fahrzeug gezeigt. Bei der Batterie 1 handelt es sich um eine Antriebsbatterie eines Elektrofahrzeuges, eines Hybridfahrzeug oder eines mit Brennstoffzellen betriebenen Fahrzeuges.In the single figure is a cross section of a battery 1 shown for a vehicle. At the battery 1 it is a drive battery of an electric vehicle, a hybrid vehicle or fuel cell powered vehicle.

Eine solche Batterie 1 ist üblicher Weise im Bereich eines Fahrzeugbodens angeordnet, wobei die Batterie 1 mit ihrer Längsausdehnung senkrecht zur Längsausdehnung des Fahrzeuges angeordnet ist.Such a battery 1 is usually arranged in the region of a vehicle floor, wherein the battery 1 is arranged with its longitudinal extent perpendicular to the longitudinal extent of the vehicle.

Die Batterie 1 weist ein rechteckiges Batteriegehäuse 2 auf, in welchem fünf Module M1 bis M5, die jeweils aus einer Anzahl nicht näher dargestellter Einzelzellen bestehen, angeordnet sind. Mit anderen Worten ist eine vorgebbare Anzahl von Einzelzellen zu einem Modul M1 bis M5 zusammengefasst.The battery 1 has a rectangular battery case 2 on, in which five modules M1 to M5, each consisting of a number not shown individual cells, are arranged. In other words, a predeterminable number of individual cells is combined to form a module M1 to M5.

Bei den Einzelzellen handelt es sich beispielsweise um Lithium-Ionen-Zellen, wobei in Abhängigkeit der Ausbildungsform der Einzelzellen in deren Zellinneren ein Elektrodenfolienstapel oder ein Elektrodenfolienwickel angeordnet ist.The individual cells are, for example, lithium-ion cells, wherein an electrode foil stack or an electrode foil wound is arranged in the cell interior, depending on the form of formation of the individual cells.

Die fünf Module M1 bis M5 sind nebeneinander in dem Batteriegehäuse 2 angeordnet, wobei die Module M1 bis M5 als Ganzes betrachtet eine Rechteckform aufweisen.The five modules M1 to M5 are juxtaposed in the battery case 2 arranged, wherein the modules M1 to M5 considered as a whole have a rectangular shape.

Durch die Anordnung der Batterie 1 quer zur Längsausdehnung des Fahrzeuges sind die langen Gehäuseseitenwände 2.1 des Batteriegehäuses 2 in Stoßrichtung R bei einer das Fahrzeug betreffenden Frontal- oder Heckkollision angeordnet. Wirkt die Kollision auf die Batterie 1, besteht die Gefahr, dass sich das Batteriegehäuse 2 deformiert.By the arrangement of the battery 1 transverse to the longitudinal extent of the vehicle are the long housing side walls 2.1 of the battery case 2 arranged in the direction of impact R in a vehicle related frontal or rear-end collision. Affects the collision on the battery 1 , there is a risk that the battery case 2 deformed.

Um im Wesentlichen ausschließen zu können, dass die aus den Einzelzellen gebildeten Module M1 bis M5 bei einer Frontal- oder Heckkollision des Fahrzeuges aufgrund der Deformation des Batteriegehäuses 2 beschädigt werden und dadurch beispielsweise ein Gesundheitsrisiko für Fahrzeuginsassen und Personen im unmittelbaren Umfeld der Batterie 1 besteht, sind die Module M1 bis M5 kollisionsbedingt in eine Stoßrichtung R verschiebbar in dem Batteriegehäuse 2 angeordnet. Dabei sind die Module M1 bis M5 mittels z. B. am oder innerhalb des Gehäusebodens 2.2 nicht gezeigter verschiebbarer Anbindungspunkte verschiebbar gelagert. Alternativ oder zusätzlich sind die Anbindungspunkte deformierbar, woraus eine Verschiebung eines oder mehrerer Module M1 bis M5 im Kollisionsfall resultiert.In order to be able to essentially rule out that the modules M1 to M5 formed from the individual cells in the event of a frontal or rear collision of the vehicle due to the deformation of the battery housing 2 damage and thus, for example, a health risk to vehicle occupants and people in the immediate vicinity of the battery 1 exists, the modules M1 to M5 are collision caused in a shock direction R displaced in the battery case 2 arranged. In this case, the modules M1 to M5 by means of z. B. on or within the housing bottom 2.2 slidably mounted not shown sliding connection points. Alternatively or additionally, the attachment points are deformable, resulting in a shift of one or more modules M1 to M5 in the event of a collision.

Zur Realisierung einer kollisionsbedingten Verschiebung sind die Module M1 bis M5 zu den langen Gehäuseseitenwänden 2.1 als auch zu kurzen Gehäuseseitenwänden 2.3 des Batteriegehäuses 2 beabstandet angeordnet, so dass freies Volumen zur Verschiebung der Module M1 bis M5 vorherrscht.To realize a collision-induced displacement, the modules M1 to M5 are the long housing side walls 2.1 as well as too short housing side walls 2.3 of the battery case 2 arranged spaced so that free volume for displacement of the modules M1 to M5 prevails.

Dazu sind Abmessungen des Batteriegehäuses 2 in Bezug auf seine Länge sowie auf seine Breite, also die Länge der Gehäuseseitenwände 2.1, 2.3 größer gewählt als die Abmessungen hinsichtlich der Breite und der Länge eines aus den nebeneinander angeordneten Modulen M1 bis M5 gebildeten Blockes.These are dimensions of the battery case 2 in terms of its length and on its width, ie the length of the housing side walls 2.1 . 2.3 greater than the dimensions in terms of the width and the length of a block formed from the juxtaposed modules M1 to M5.

Zudem sind die Module M1 bis M5 jeweils mit sich gegenüberliegenden Schmalseiten parallel zu den langen Gehäuseseitenwänden 2.1 und in Stoßrichtung R bei einer Frontal- oder Heckkollision verschiebbar angeordnet.In addition, the modules M1 to M5 are each with opposite narrow sides parallel to the long housing side walls 2.1 and slidably disposed in the direction of impact R in a frontal or rearward collision.

In einer möglichen Ausführungsform sind die Module M1 bis M5 durch die aus der Kollision resultierende Deformation der jeweiligen langen Gehäuseseitewand 2.1 selbst verschiebbar. Die Gehäuseseitenwand 2.1 wird aufgrund der Kollision deformiert, wobei die Deformation auf die Anbindungspunkte und/oder die Module M1 bis M5 wirkt, so dass die Module M1 bis M5 mittels der verschiebbaren und/oder deformierbaren Anbindungspunkte innerhalb des Batteriegehäuses 2 verschoben werden.In one possible embodiment, the modules M1 to M5 are due to the resulting from the collision deformation of the respective long housing side wall 2.1 self-displaceable. The housing side wall 2.1 is deformed due to the collision, the deformation acting on the attachment points and / or the modules M1 to M5, so that the modules M1 to M5 by means of the displaceable and / or deformable attachment points within the battery case 2 be moved.

Alternativ oder zusätzlich werden die Module M1 bis M5 bei einer Kollision des Fahrzeuges über die verschiebbaren Anbindungspunkte aufgrund der Masseträgheit innerhalb des Batteriegehäuses 2 verschoben.Alternatively or additionally, the modules M1 to M5 in a collision of the vehicle on the sliding connection points due to the inertia within the battery case 2 postponed.

Dadurch, dass die Module M1 bis M5 kollisionsbedingt verschiebbar in dem Batteriegehäuse 2 angeordnet sind, sind die Module M1 bis M5 selbst bei einer Kollision des Fahrzeuges weitestgehend gegenüber einer Deformation und einer aus der Deformation resultierenden Beschädigung geschützt. Somit ist nahezu vermieden, dass thermische Reaktionen und/oder ein Kurzschluss innerhalb der Batterie 1 auftreten.Characterized in that the modules M1 to M5 collision caused displaceable in the battery case 2 are arranged, the modules M1 to M5 are largely protected against deformation and damage resulting from the deformation even in a collision of the vehicle. Thus it is almost avoided that thermal reactions and / or a short circuit within the battery 1 occur.

Darüber hinaus ist mittels des kollisionsbedingten Verschiebens der Module M1 bis M5 einem Versagen einer Regelung und/oder Steuerung entgegengewirkt, so dass eine Diagnosefähigkeit der Batterie als Ganzes und/oder der Module M1 bis M5 erhalten bleibt.In addition, by means of the collision-related displacement of the modules M1 to M5, a failure of a control and / or control is counteracted, so that a diagnostic capability of the battery as a whole and / or of the modules M1 to M5 is maintained.
